It's even a bit better, you can make the folders in windows/linux, copy the files on the SD card and load the stuff in MSX basic via a loader or something.

All you have to do is set DIP switch 5 to ON/1 to have SD harddisk support. With DIP switch 5 set to OFF/0 you can put an external FDD in one of the cartridge slots and have it working like on the old MSX.

All I need to do then is:

-format the SD card (FAT 12/16)
-put the DOS2 files (command.com, etc.) in the root directory
-copy .rom files to a directory that includes the MGLOAD file so I can load standard roms and megaroms
-make directories containing different progs like if it were a large harddisk
-Turn DIP switch 5 to ON (and DIPs 7 and 8 to 01 in order to load megaroms too)

Now the machine should start in DOS2, then I'd need loaders as you say, but how to start a .bas file in DOS (I've never worked under DOS). Do programs need specific loaders or something like that? Thanks in advance again (sorry, I'm a bit nerd) Tongue

you just type something like "basic" in the dos prompt i think, but i have to admit i am not sure either.

oh, and make sure you copy the dos files with fat16 support onto the SD card Wink

Try to change the DRIVE letter and the directory first.
Later type:

BASIC filename.BAS

(could be any other extension or even a loader with a blank extension.)

You can even make BAT files with the text:

BASIC loader.BAS

If you make a bat file you only need to type the name of the BAT file to execute the BASIC loader, no need for any extension.
example:

AUTOEXEC.BAT

Type :
AUTOEXEC

Autoexec.BAT files are easy to make.
All BAT files are plain ASCII texts.

If you want other forms for the DOS try the COPY CON command:
COPY CON
(Control+Z to end the file)
to make the loader.bat file.

Later type :

TYPE loader.bat

Is it necessary under the 1chipMSX to use the next poke before loading games?

poke -1,(15-peek(-1)\16)*17

not to load rom files, but it is to software that uses the memorymapper of the msx2 and that is not programmed so well (usually cracked mega-roms that load from a basic loader)

Thanks again, I think I'm ready to fill the SD card with software Tongue Next step will be to connect a MSX mouse and test SymbOS Big smile

Guys,

Is there any way to save date / time in OCM or does it not emulate CMOS? I have to set time / date every time I boot up MSX-DOS2... Question
